I have been using this Netgear R8000 router for three months without any problems. Recently, it cannot access the Internet  without rebooting it. While it is unable to connect to Internet, I am still able to connect to the router, I have no idea what is the problem and I never change any setting since the first day I set it up. I have to reboot it every day or every two days now.

I have configured two internal subnets NATing with WAN interface. I want to limit the bandwidth for subnet A 30 Mbps and the rest for others.

Subnet A 192.168.7.0/24
Subnet B 192.168.8.0/24


Any help is appreciated.

We have 2 network cabinets at different ends of the building - connected by 2 x Cat5e UTP cables. When I tested the cables I found pins 7 and 8 on both cables shorted. Both cables are connected into a single switch at either end.

Why would a previous IT technician do this.?

Is this some form of strange aggregation of the lines.?!

As far as I was aware pins 1 & 2 transmitted, 3 & 6 received. Pins 7 & 8 may be used for PoE..

I'm baffled.. any help would be greatly appreciated.

Hi Experts,

I am using SpiceWorks and it cant authenticate a router on the network. I have the IP and credentials but its asking that I select one of the following:

and I thought it was SNMP which shows me the following:

but I did not set this router up and I don't even know where I should be looking.  any ideas of where I should be looking, or if SNMP is even the option I need. I am a novice when it comes to this so all help taken.

Hi,
 
I am trying to install a fiber optic cable to run about 150M between buildings. I have never done this before. I have not ordered the cable yet. How to terminate it? Should I try it myself? Rent a fusion splicer? If  I get the cable pre-terminated I will have to cut huge holes in the wall to get all the tips through. I need about half a dozen terminations or splices. I have never done it before and might never need to do it again.

Equipment
Already have: One switch with 2 SFP ports
Will get:
150 Meters of OM1, 6 strand, indoor/outdoor distribution cable
4 SFP modules with LC connectors
2 SFP media converters to Gigabit Ethernet
LC patch cords
Would like to put in some nice fiber wall jacks or patch boxes

In Windows, if I type Getmac command, I can get the Mac addresses of the adapters (physical and virtual)I have connected to the computer.
However, How would I know which Mac address is the burned-in Mac address and which is the mac address generated by the OS ?

Thanks

I have  a Netgear R6250 with dual band capability. Lately any device on the 2.4 Ghz band bounces up and down constantly. Doing a continuous ping to google I get responses one minute, then time outs, then host not reachable, then back again, all within the span of about a minute. This is happening on multiple devices (Three different laptops, two smart phones.) The 5 Ghz band, however, which almost every other device uses, is up and solid and never wavers.

This isn't a huge deal because every device I own but one can support the 5 Ghz band so it's not an emergency. Still, I'd like to figure out what the issue is and if it's a hardware issue or something else. I have seen some message boards complain about the opposite - that 5 Ghz drops and 2.4 is OK but not for my particular problem. I recently upgraded to the latest firmware and have factory reset it.

Some more info:

Router: Netgear R6250
Firmware: V1.0.3.12_10.1.8
Attached devices: 6-8 wireless, one wired. Only one of these can't use the 5 Ghz band.
Channel - I put it on channel 9 to make sure it wasn't interference but I'm still having the same issue.


The issue only started a few weeks ago. Before that everything was running fine on either band. In fact, I had done a full factory reset for something else and afterwards the problem started, although this could just be a coincidence.

Greetings. AT&T is offering us a very good deal on high-speed business fiber.  Their sales rep e-mailed me the following:

"Now when you do have a conversation with your building manager, please assure him that the fiber that AT&T will be installing is the non-regulated fiber that is used similar to AT&T's Uverse service.  Highlight the fact that it is the "non-regulated" fiber circuit."

Can someone shed some light on what the difference between a "regulated" and "non-regulated" fiber circuit is ?  I have no idea.  The rep said something about "regulated" fiber going through a building riser company and that the other tenant in the building also had a non-regulated installation.  They are on the 2nd and 3rd floors.  We are on the 4th.   Is it just installed differently ? Safer ?

The service is symmetric fiber with a 4-hour SLA. and a small pool of static IPs.   I presume it's business-class service.

Thanks much.

Hi Everyone,

I have never used or setup a NAS before. I am looking at buying a NAS to sit on a workgroup with around 10 PC's, they do not have an amazing internet connection so I don't want to use a cloud solution and they currently communicate between each other and save documents onto a local PC (shared folders). which is old and will probably pack up.

so I am guessing that what I am looking for (because the LAN speeds are all fine) is a NAS? unless someone can suggest an alternative which is better.

but here my problem, I have never set one up before. just some HDD's with an UI + NIC? do I need to look out or check anything?

Whats the best way to test Bandwidth restrictions. I have set HTTP and HTTPS restrictions on a watchguard firewall on 4 different VLANs.

Will a speedtest.net test not work?

Where is a Mac Wireless NIC Driver Version Located?

I'm setting up a virtual wireless controller using the guide provided here: http://www.labminutes.com/wlc0001_vwlc_7_3_vmware_installation

The narrator mentions your VMware being licensed for "Remote Virtual Serial Port Concentrator". I don't have a license level that supports that feature and upgrading is too costly at this point. How else can I get remote CLI access to this device? Is there some way to set up SSH access on that machine with the aforementioned technology?

Any help is appreciated.

I have two networks in one physical location.  

Network 1:
Juniper SSG140 /w Public Interface IP
192.168.110.x

Network 2:
SonicWall TZ300 /w Public Interface IP
192.168.113.x

The two firewalls are on the same rack.  how do I connect them so both networks can see one another?  Can I run an ethernet cable between the routers?  Thanks.

Hi Experts,

just a quick question, I have 2 routers and 2 internet connections at a site. 1 internet connection + Router is dedicated to a 3rd party Server called CDL which is used in insurance for EDI transmissions. the 2nd internet connection + Router is dedicated to the IP Phones / Internet Access for PC's.

the CDL server has a static LAN IP.

I am a novice when it comes to networking but I have a good overall understanding.

if the PC's and server are using different routers how are they going to be able to talk together? they will be effectively on different LAN's.

NOTE: this is regarding 4 x IP Phones, 4 X Win7 PC's, No Server / No Domain.

We have an HP SC08Ge SAS/SATA JBOD controller installed in an HP DL585 G6 server.   No matter how we configure it, we cannot get this JBOD controller to see individual attached SATA drives.  

We attempted to use an SFF-8088 cable on the SC08Ge external connector, and this cable breaks out to four separate ESATA connectors.  We plug one of these into an external SATA drive container, but the drives are never seen.

We also tried to connect the controller to an MSA2024 with straight through multiport SAS connectors, and unfortunately this also fails to see any drives in the MSA2024.

There is some basic point about this controller and how it is used and cabled that we are not getting.  Can someone please advise?

OS is Windows 2008 R2.   We use Disk Management and Rescan option to look for new drives.  Nothing appears in Disk Management.  When we reboot the system, the SC08Ge BIOS also fails to announce any attached devices.
